珠海横琴岛位于珠江三角洲断陷区南缘,珠江磨刀门出海口的东北侧,场地内沉积了巨厚的淤泥软土。对场址内原位测试、室内土工试验得到的深厚淤泥层的物理力学指标和强度参数进行了相关性分析,得到了该场区软土室内试验、原位测试获得的物理力学指标间的相关关系,并将其应用于工程实践,取得了良好的效果。研究方法和成果对于指导类似软土地区的工程有重要的指导意义。 Zhuhai Hengqin Island is located in the southern margin of the Pearl River Delta fault zone, the Pearl River Shaodong port northeast of the sea, the site deposited a huge thick silt soft soil. The correlation between the physical and mechanical parameters and the strength parameters of the deep silt layer obtained from the in-situ test at the site and the indoor geotechnical test was carried out. The correlation between the physical and mechanical indexes of the soft soil in the field and the in situ test was obtained Relations, and apply it to engineering practice, and achieved good results. The research methods and achievements have important guiding significance for guiding the project in similar soft soil areas.
